[Search Connectors] - Remove duplicate agent policy when connector is created as an integration (#208123)

## Summary

With Agentless Connectors, users can create a connector without a
`connector_id` or a `connector_name`, so when a policy is created
without them, they won't be skipped anymore.

The connectors do end up getting their `connector_id `updated to be the
policy's `package_policy_id`, so when the check is done whether or not
to deploy native connectors and create a policy, there's an an
additional check for whether `connector_id` is the `package_policy_id`.
